GPS / GNSS Jammers for Drones & UAS

GPS jamming is a technique employed in counter-UAS (unmanned aerial systems) operations to deal with rogue drone threats. They work by interfering with GNSS satellite signals, including GPS, GLONASS, Galileo and Beidou, which are used by drones for navigation.

Drone GPS and GNSS jamming devices may be used as part of a complete counter-drone solution, which may also include radar-based and electro-optic detection systems, drone capture nets, or hard-kill kinetic effector devices.

How do GPS Jammers Work?

Drone GPS jammers emit signals on the same frequencies as GNSS satellite signals. These signals are stronger, meaning that they will drown out the legitimate signals and essentially cause the drone’s GPS receiver to stop working. This can cause the aircraft to crash or drop out of the sky.

Advantages & Regulations

Drone GPS jamming can be used to target autonomous drones, which may not be transmitting or receiving signals between themselves and the ground control station, and thus will not be affected by RF signal jammers.

It’s important to note that the use of drone jamming technology is typically illegal in many countries due to potential interference with critical systems such as telecoms, aviation and emergency services. Also the disruption of drone signals can pose risks to both people and property, making it vital that such technology is only used within applicable regulations, failure to so could result in severe penalties.

The Difference Between Jamming & Spoofing

Although often referred to interchangeably, GPS jamming and GPS spoofing are two distinctly different technologies, both used to mitigate drone threats. Whereas GNSS jamming interferes with and disrupts communication signals, spoofing technology is used to deceive GNSS receivers into accepting false information and therefore terminating flight.
